Amazon US launched a dedicated PlayStation Network store on its website today, meaning customers can purchase download codes for PS4, PS3, and Vita games and DLC via the online retailer. Amazon has sold download codes for platforms like PC and Mac for a while now, but Sony is the first console manufacturer to join the retailer's digital party, making a fashionably late but certainly well-timed entrance. According to Amazon, there are over 100 pieces of downloadable PlayStation content available via its storefront at launch.

Amazon and Sony are marking the launch by chucking in $5 PSN credit (redeemable at Amazon of course) with selected purchases, including full games and season passes for Assassin's Creed 4, Batman: Arkham Origins, The Last of Us, and Battlefield 4.

Also for one day only, starting today at 9AM PT and ending tomorrow at the same time, you can get the $5 PSN credit with any PS4 game purchase. Then there's the Buy 2 Get 1 Free offer going on PS4 launch games. In other words, Amazon is very keen to be a part of your PS4 launch party this week.

The PSN storefront is restricted to Amazon's US branch for now.
